PROCEDURE

实验过程

A suspension of benzyl 4-acetyl-3-(4-cyanophenyl)-5-oxo-2-({[3-(trifluoromethyl)phenyl]amino}carbonyl)hexanoate (7.5 g, 15.6 mmol) (Example 5A), anhydrous magnesium sulfate (15 g, 125 mmol) and Amberlyst 15® (7.5 g) in ethanol (300 ml) is stirred overnight at reflux. The reaction is cooled to room temperature, filtered through a pad of celite and concentrated in vacuo. The residue is purified by flash chromatography over silica gel 60 with cyclohexane/ethyl acetate mixtures as eluent.
